FAQ
What do you need from me to start the React.js project?
To get started, I need your project requirements, UI design (Figma/PSD/XD) if available, content, and any API details. If you don’t have a design, I can help you plan a clean and modern React UI/UX.
Do you develop fully responsive React websites?
Yes. All React.js and Next.js frontends I build are fully responsive, mobile-friendly, and tested on desktop, tablet, and mobile devices using Tailwind CSS or Material UI.
Can you convert Figma or design files to React.js?
Absolutely. I can convert Figma, PSD, or Adobe XD designs into pixel-perfect React.js or Next.js UI with clean, reusable components and optimized performance.
Is the React code SEO-friendly and optimized?
Yes. I follow clean code standards, performance optimization, and use Next.js SEO-friendly architecture to ensure fast load times and better search engine visibility.
Do you provide revisions and post-delivery support?
Yes. I provide revisions based on the selected package and offer post-delivery support to ensure everything works smoothly. Long-term support is also available if needed.
Can you work on existing React projects or fix bugs?
Yes. I can fix React.js bugs, improve UI/UX, refactor code, enhance performance, or add new features to existing React or Next.js applications.
What does post-delivery support include?
It includes bug fixes, minor adjustments, guidance on usage, and assistance with any issues related to the delivered work.
Will you be available if I need help in the future?
Yes, I believe in building long-term working relationships. I remain available to assist you even after project completion.
